Motion Capture System Study on Human Balance

In clinical practice, many tests are carried out to assess the state of the laby-rinth and the ability to maintain balance by patients. There are performed tests such as the Unterberger, Fleck, Romberg test or various posturography examination methods. These examinations are carried out in a clinical set-ting, using specific procedures, which, however, are not unequivocally sys-tematized, and the performance of the test - and therefore its results - de-pends on the experience of the person conducting it. The purpose of this study is to use the motion capture system to carry out selected balance tests, thanks to which it is possible to observe previously unnoticed parameters and to objectively evaluate the tests performed. The research was carried out using the BTS Smart system and dynamometric platforms on a group of healthy young adults. The paper presents a precise description of the tests performed and the method of using the motion capture system capabilities to support the research on balance. Parameters allowing for a precise assessment of the quality of test execution were also proposed and the results obtained with their use were presented for the examined group of people.
